The Mumm Lab

The research conducted in the Mumm Lab (Dept. of Ophthalmology, Wilmer Eye Institute) is focused on understanding how neural circuits are formed, how they function, and how they can be regenerated, to develop new therapies for retinal regeneration. Toward that end, we investigate the development, function, and regeneration of disease-relevant neurons and neural circuits responsible for vision. An emphasis is placed on translating what can be learned in regenerative model systems to develop novel therapies for stimulating dormant regenerative capacities in humans, Therefore, we apply what we learn from a naturally regenerative species, the zebrafish, toward the development of novel therapies for restoring visual function to patients. We place an emphasis on unique perspectives zebrafish afford to biological studies, such as in vivo time-lapse imaging of cellular behaviors and cell-cell interactions, and high-throughput chemical and genetic screening. We have pioneered several technologies to support this work including multicolor imaging of neural circuit formation, a selective cell ablation methodology, and a quantitative high-throughput phenotypic screening platform. Together, these approaches are providing novel insights into how the degeneration and regeneration of discrete retinal cell types is controlled.
